' Application filed February 2 To all whom it'may concern:

Be it known that I, FREDERICK?. Ros- BACK, a citizen of the UnitedStates, residing at Benton'Harbor, in thecounty of Berrien and State ofMicliigan, have invented a new anduscful Improvement' in Brickma 'nv- Machines, of which the following is a specii` cation. v

. My invention relates to improvements in the class 'of rotary machines for making brick,` or blocks for building purposes, more particularly out of cement or concrete, and' employing to that end an intermittently revolving drumequi ped with-molds at intervals, whereby eacli partial rotation of the. drum brings one mold into position for feed,-` ing and compacting into it the material'to form one or more bricks or blocks, another mold into osition to have'the material, previously fe and compacted into it, pressed to complete the moldedarticle, rand still, an-

v other Irold into position toV deliver' the previously completed article. y, l

.The object of my invention is, generallyy stated, tol improve the `construction and' manner of operation of machines in the class referred to, by novel organizations fof 4parts and novel features, to the primaryend -of im roving-the product of such machines.

The bed 31 of the machineL is a substantial ystructure of rectangular shape, and'is shown t best in Fig. 23. It is formed, for the sake of l.38' to extend parallelwith eac facility in handling it,of twosimilar longitudinal halves, each. consisting, for the sake of lightness,`of a hollow casting as to the main portion of the frame, with narrow hollow/extensions 32 on one end ,and the sections are bolted together through their abutting inner walls or webs, as shown in Fig. 9. To the top of each-'side-rail of the bed is bolted a similar frame 33, preferably formed intwo longitudinal sections bolted together through thelr contiguous flanges, as'- represented, this framework so rising from the bed affordingI bearings for parts of the mechanism hereinafter described. A yoke-shaped head 34 rises from the extreme outer end of the nar- .row` extension 32 of the bed, also for supbases,in the preferred form' illustrated, con-` siste of three -cast-metal arms 43 bolted through their base-flanges rigidl to the hub form "the intervening longitudinal spaces 44', 44, (Fig. 19) for thek purpose hereinafter ex lained. On the outer end of each arm 43 is'l olted a plate 45, preferably of chilledA iron -to present a smooth outer surface and afford y a-.nrold-bottom. The Walls of each-mold 46 formingl a' rectangular structure', consist of end-plates 47, 47, each having'a chilled-iron lining48 and sides, each consisting of a'plul*ralitylas three) of similar plates 49, with -tongues 50 on their ends to-iit into recesses in the lining-plates and similar 'recesses in partitions 5] and 52, preferabl- .of.chillediron,

which divide the mold into t ee similar comother and partments 53, each of the shape of a brick or other article to be molded. lhe sections of .the mold-walls are securely fastened together by bolts 54 passing through the plates 47 near their corners, through the side-plates 49 and the interposed partitions and lining-,

lates. 'lhe wall-structure of each mold conorms to and iits snugly, but' yieldingly, about theoutcr end of the respective series of arms 43, the end-plates being provided with guiding tail-pieces 55 to work between flanges 56 on the sides of, the outer arms 43, each tail-piece carrying near its inner end, on a. boss 57 there provided, an anti-friction roller 58 for a purpose hereinafter stated. The circumferential wall'of the drum 37 is composed of similar segmental plates 59 carrying inwardly projecting perforated ears 60, at in-` tervals, each segmental-plate extending between a pair of t e molds, to effect complete closurevof the drum circumferentially between molds, the ends of the drum being closed by similar heads 61 bolted to the segmental sec-- tions 59 through theirears 60, andvalso bolted ICO itsouter end in. proximity to the mold-bottom 45. In the shaft 36 is formed a steaminlet assage 66 leading from one end of the shaft engthwise andcentrally thereinnearly to its transverse center, and having coupled toits outer enda steam-supply pipe 67 communicating with a supply o live-steam (not shown). .At its 'inner end, the duct 66 is directed to extend. transversely through the shaft 36 and hub 38 to a pipe 6 8 (Fig.2) carrying an annular steam-pipe 69 having manifolds 70 extending yhorizontally from it along corresponding sides of the4 respective arms 43 of the mold-bases; and each manifold 7 0 has a nozzle 7 1.extending at a right-angle from it ric into a passage 63 at its inner end. Another annular steam-pipe, like the pipe 69, is supported at the opposite end of the hub (see Fig. 17) by a ipe 72 communicating through the huband s aft 36'v with an exhaust-duct 73 leading lengthwise and centrally of the shaft, from near the transverse center thereof to its opposite end, whereiit is coupled 'with an exhaust pipe 74. This second annular steampipe, whlchfis provided for the exhaust, and which is denoted as 75 in the drawing, has manifolds 76 projecting horizontall from it at intervals to extend along the si es of the arms. 43 opposite the sides thereof along which the manifolds 70 extend, each manil fold v76 communicating with a steam-passage 64 through a nozzle- 77.

A supplementall frameA consisting of par# I allel horizontal bars 78, 78 bolted to the ends of the side-frames 33 and connected at their outer endsby a ,tie-bar 79, forms the guiding support for a tamper-housing 80, provld-ed on its sides with flanges 81, which embrace the lbars 7 8, to permit the housing to slide thereon. 't In the upper part of the housing, at vits oterend', is )ournaled a shaft 82 carrying a aii" of outer eccentrica 83, a pair of interme-v t arms 88 l 1ate eccentrics 84 `and a central eccentric 85 l (see Figs. l`-12.).

A tamping-head 86, containing longitudinal slots 87, has a pair of tending backward from it, at

" which it is sup orted by hangers 89, 89 susecting en its upper wall. lThus the tamper 86 is supported by the links -to adaptit to be reciprocated in a horizontal plane. With the tamper 86 eccentrically connected with the shaft 82, are co-operatively vassembled two other tampers861 and 862, the three forming a set, and all being alike' except that the tamper 861 has its rod-connections 92 with the eccentrics 84'7 while the' tam er 862 has its central rod-connection with t e eccentric 85; and

that the head of each tamper 861 and 8 '62 isprovided in the section thereof divided by the slots 87, 87, with a centrally perforated dish-like cavity 94, for a pur ose hereinafter described. Another set of t ree -tam ers, in

all articulars like the set thereof t ius de` scri ed, except that eachis provided withthe .perforated concavities 94,v forms the lower The members of this lower setv tamper-set. l 861" 8611 and 8612 are connected by their rods,

` like those of the upper set, with eccentrics on a lower shaft 821, journaled in the rear end of the housing in vertical line with the shaft 82. Instead of being sus ended, like the.

members of the upper set, t ose of the'lower set are pivotally supported at corresponding .points, by links 891, 931 extending upwar from the lower wall of the'housing, but like the hangers 89, 93, to cause the lower tam ers to reciprocate in horizontal a lanes,

- heads of the tarn ers are so c ose together that' they rub against each other in reciprocating. On the shaft 82 is a belt-pulley 95,l

and asimilar belt-pulley 96`is provided on the shaft 821,-both pulleys being connected,

for driving the shafts, with an overhead drive-shaftlnot shown). l

Between thehousing 80 andl drum 37 is pivotally connected with its pro-Y s hangers 93 pivotally suspended, ike the hangers 89, in the' housing 80from mountedoveran inlet-opening, across which I the tampers reciprocate, a box or. chute 97 for directing into the pathsxof the tampers the mo1stmaterial98 (as cement or concrete) .out of -which thearticles to be produced by Athe machine are formed, this material being supplied' by gravity through 'a -hopper 99, v surmounting th'e box. On the forward side [of the box 97 is a springressed scra er 100 l(Figs-13 and 14), ada te to bear yie dingly against the 'surface o the drum; and below the tampers is supported on brackets 101, a rece tac e 102 to` catch the material which wor thus prevent the waste thereof.-

downwardly through the tampers andJ To the supplemental-frame bars 78 are bolted,to'depend therefrom, ears 103. .'On thelower ends of these ears are fulcrumed, at

104, similar levers 105, each having its upper l end bifurcated to embrace astrid` 105/pro# jectingfrom a side of the Ahousing 80,` as clearl shown in Fi 1 and 9, whereby turn-A ing ofythe levers sli es the housing on itssuptions of the'levers 105 are'adjustablycon` nected'links 106, which are themselves adv ljustable, these links being ivotallyv con-- arallel bars,

Thls table' is shown in Fig, 29 and is provided with three longitudinal grooves 1701 in its upper side to receive the ribs 170 of the pallet and seat the latter stably.' On one end of the table a projecting IIO 28, and consisting of a operation of the mac e. .The l cam-fin er 173 is provided for a'lpurpose hereina terexplained; and on the underslde "heftabl'e, and centrally thereof, 1s rlgidly of sec red at-its head 174, a guiderod v175 to depend vertically therefrom and reciprocate in a guide-tube 176 provided on a crossrbar 177 bolted at its ends on the-tops of Zthe sides of the` base 31. Am arm' 178 embraces at one bifurcated end the`head '174 and 1s ivotally connected therewithA by -a pln 179, t e o posite end of this bar havinga bifurcated e'ad throw of the table y172 is regulated and the. spring-deviceon the arm 17 8 renders the en` gagementdof the table with the articles r'e, ceived upon it', as hereinafter described,- yielding to avoid impairment of the articlesI as i-n the event of any*accidentalobstruction tothe action of the table.

To the outer face of the cam-head 165 is.

livotally connected one en d of a .link 189 aving its opposite end dpivotalllconnected with a bar 190 mounte to sli e longitudinally in bearings 191 projecting from a side .of the frame 33. A stud 192 depends rigidly from this bar between its ends and has journaled on its lower extremit a link 193 con vnectedwith a species of bel -crank lever consisting of an arin 194 pivotally connected with said link and terminating in a sleeve 195 rotatabl surrounding a stud4 196 'rising from the be 31, and/ani arm 197 extending f from said. sleeve. 'A' link 198 is pivotally connected at one vend with the free end of the bell-crank arm 197, and terminates at its opposite end in a collar -199 rotatably confined about a stud 200 de ending from the base of aslide 201 provided) with lateral flanges 202 at which it seats on the horizontal webs ofthe rails forming the track 1.66.

To Jfacilitate explanation of Ithe operation of the delivery-mechanism of the machine a' pallet 169 must be sup osed to be imposed upon the table 172, an another pallet to be imposed on the track 166-between the table' and the stack of pallets in the nack 167 (see Fig. 6.). The movements of the machine are -so timed and the cam 165 is of such shape that just prior to the stoppage of the drum the cam 'rocks the shaft 162 to raise the table 172 to within a small fraction .of an inch below the mouth of the-mold. then registering' at the end of each partial revolution thereof,

the Wall-structure of this mold is raised' by the action of the ring-sections '156 in the the table reaches this lower position, the' ac- .manner already described, to free the mold tion of the cam 165 moves the bar, 190 "to 1 direction to advance `the slide 201 und-erneath the rack 167 and inslidin to encounter the lowermost let in the stac thereof and al -slide ital-ongtiie track 166 against the next j pallet nits path, which, in turn, engages the 9o Y pallet on the table and moves that pallet,

with the bricks u on it, off the table u on the track 1661, wv-ereon it may be furt er moved by th succeeding operation or operamechanism, like the o eration just descri ed and be thus eventutions of the deliver a lytransferred to asuitable conveyor, or the de lvered pallet with-the bricks upon it may immediatelv be taken -oii the track 166.

The described sliding action of the plate 201 jooobviously positions on the table 172 the next succeeding pallet, bringing adjacent thereto the pallet previously moved from beneath the stack. The'continued rotation of the cam returns the pusher-plate 201 to its 1o 5 initial position, -as represented in Fig. 23, to take it from beneath .the stack and permit thelatter to drop Iupon the track, and also', just before the drum completes another parnv tial rotation, turns the rock-shaft `162 to 11o raise the .table 172 into position to receive the set of bricks from thenext mold brought into registry with it. lIn the rise of the table, the-cam 173 u on it will force back upon the track 166 t thereon in thee'vent that in feeding the lastnamed pallet, it should be moved so far as to cause its edge t overlapthe adjacent edge of the table. v

The described operation of the delivery izo mechanism affords the vmaterial advantage of avoiding the subjection of the green product to any rubbing or dragging action, which would tend to break or crack it.
